BATON ROUGE - The American Civil Liberties Union of Louisiana is suing to block enforcement of a new state law that limits sex offenders' access to social networking websites and other online forums.

The federal suit filed Monday in Baton Rouge claims the law is overly broad and violates the free speech rights of sex offenders.

The ACLU says the law, which took effect Monday, likely targets sites like Facebook and MySpace but also blocks access to newspaper sites, job databases and other websites that allow users to communicate.

The group is asking a federal judge to immediately block enforcement of the law.

Gov. Bobby Jindal, who signed the measure into law, and Louisiana Attorney General James "Buddy" Caldwell are named as defendants in the suit.
